Research on Electrical Automation Monitoring Technology for Hydropower Plants Based on LCU
This paper takes the control of electrical automation units in hydropower plants as an example,a monitoring system for electrical automation in hydropower plants based on LCU is proposed.Based on the local control unit LCC and programmable PLC as the core,Ethernet is built between the system workstation and the automation unit to construct an automatic generation control(AGC)monitoring system platform.By analyzing and calculating the operation data of the electrical automation unit,fault signals are detected in a timely manner,and effective redundant control is adopted to ensure the stable operation of the hydropower plant unit.
